Blaine stepped up to the microphone and addressed the crowd at Callbacks, “This song is dedicated to my ex.” 

I stay out too late

Got nothing in my brain

That’s what people say, mm-mm

That’s what people say, mm-mm

He looked across the room and located his ex-boyfriend. Blaine thought they were having fun getting to know each other, but apparently, Kyle didn’t believe in monogamy. 

‘Cause the players gonna play, play, play, play, play

And the haters gonna hate, hate, hate, hate, hate

Baby, I’m just gonna shake, shake, shake, shake, shake

I shake it off, I shake it off

Kyle frowned at him, but Blaine ignored it. He’d spotted a boy from his stage-combat class that interested him more. 

My ex-man brought his new boyfriend 

He’s like, “Oh my god!” but I’m just gonna shake

He liked Kurt from the moment they met, but never acted on that attraction out of respect for Kyle. Feeling brave, he locked eyes with Kurt and sang the next lines directly to him. 

And to the fella over there with the hella good hair

Won’t you come on over, baby? 

We can shake, shake, shake
